Endometrioid Carcinoma: Symptoms, Causes, Diagnosis and Treatment

Written by Medicover Team and Medically Reviewed by Dr Kovvuru Bhaskar Reddy , Oncologists



Endometrioid Carcinoma is a malignant epithelial cancer that most commonly arises in the endometrium (lining of the uterus) and, less commonly, in the ovaries. It is the most frequent subtype of endometrial cancer and is often associated with prolonged estrogen exposure, obesity, and endometrial hyperplasia. Common symptoms include abnormal uterine bleeding, pelvic pain, and, in ovarian cases, abdominal bloating or a pelvic mass. Early diagnosis and prompt treatment, typically involving surgery with or without radiation therapy, chemotherapy, hormone therapy, or targeted therapy, are essential to improve outcomes and reduce the risk of recurrence.


What are the Types of Endometrioid Carcinoma?

Endometrioid carcinoma can manifest in various forms or types, each with distinct characteristics and implications. These variations may impact factors such as treatment options, prognosis, and risk factors. Understanding the different forms of endometrioid carcinoma is crucial for accurate diagnosis and appropriate management by healthcare providers.

  • Endometrioid Adenocarcinoma: A common type of endometrial cancer that develops in the glandular cells lining the uterus.
  • Clear Cell Endometrioid Carcinoma: A subtype of endometrioid carcinoma characterized by clear cytoplasm in the cancer cells.
  • Serous Endometrioid Carcinoma: A more aggressive form of endometrial cancer that arises from the serous cells of the uterus lining.
  • Mucinous Endometrioid Carcinoma: A rare type of endometrial cancer that produces mucus and typically has a better prognosis compared to other subtypes.
  • Squamous Endometrioid Carcinoma: A variant of endometrial cancer where the cancer cells resemble squamous cells, which are flat and thin.

What are the Symptoms of Endometrioid Carcinoma?

Endometrioid carcinoma typically presents with symptoms that may affect the reproductive system. These symptoms can vary in nature and severity, impacting a person's overall well-being.

Identifying these signs early on is crucial for timely diagnosis and treatment. Consulting a healthcare provider is essential if you experience any concerning symptoms related to endometrioid carcinoma.

  • Pelvic pain
  • Painful periods
  • Pain during intercourse
  • Abnormal vaginal bleeding
  • Fatigue
  • Infertility

What are the Causes of Endometrioid Carcinoma?

Endometrioid carcinoma, a type of cancer that affects the lining of the uterus, can be caused by various factors. These may include genetic predisposition, hormonal imbalances, inflammation and environmental exposures.

Additionally, lifestyle factors such as obesity and certain reproductive conditions may also contribute to the development of endometrioid carcinoma. Understanding these potential causes can help in early detection and effective management of this type of cancer.

  • Genetic predisposition
  • Hormonal imbalances
  • Retrograde menstruation
  • Immune system dysfunction
  • Environmental factors

When to See a Doctor for Endometrioid Carcinoma?

Women with abnormal vaginal bleeding, especially after menopause, persistent pelvic pain, or unusual vaginal discharge should consult a Gynecologist or Oncologist promptly.

You should see a doctor if you experience:

  • Bleeding after menopause
  • Heavy, prolonged, or irregular menstrual bleeding
  • Persistent pelvic pain or abnormal vaginal discharge

Seek immediate medical attention if you:

  • Develop heavy vaginal bleeding causing dizziness or fainting
  • Experience severe pelvic pain with excessive bleeding
  • Notice rapidly worsening symptoms or signs of advanced disease

These symptoms may indicate significant blood loss or advanced cancer requiring urgent medical evaluation.

How Is Endometrioid Carcinoma Diagnosed?

Endometrioid carcinoma is typically diagnosed through a series of medical tests and procedures designed to identify abnormal growths in the endometrial tissue. These diagnostic methods help doctors confirm the presence of endometrioid carcinoma and determine the extent of the disease.

By analyzing symptoms, performing physical exams, and utilizing various imaging techniques, healthcare providers can make an accurate diagnosis and create an appropriate treatment plan for the patient.

  • Imaging tests such as ultrasound and MRI
  • Biopsy for tissue sample analysis
  • Endometrial sampling for examining endometrial tissue
  • Blood tests to detect tumor markers
  • Pelvic exam for physical examination of the reproductive organs

What are the Treatment for Endometrioid Carcinoma?

Treatment options for endometrioid carcinoma typically involve a combination of surgery, chemotherapy, and radiation therapy. The specific treatment plan may vary depending on the stage of the cancer and individual patient factors.

Surgery is often the primary treatment to remove the cancerous tissue, while chemotherapy and radiation therapy may be used before or after surgery to target any remaining cancer cells.

Additionally, hormone therapy may be considered in some cases to help prevent the cancer from recurring. It is important for patients to discuss their treatment options with their healthcare team to determine the best course of action for their specific situation.

  • Surgery: The primary treatment for endometrioid carcinoma involves surgical removal of the tumor and affected tissues to prevent further spread and recurrence.
  • Chemotherapy: Chemotherapy may be recommended postsurgery to kill any remaining cancer cells and reduce the risk of the cancer returning.
  • Radiation Therapy: Radiation therapy can be used to target and destroy cancer cells that may have spread beyond the uterus, reducing the chances of recurrence.
  • Hormone Therapy: Hormone therapy may be employed to block or lower estrogen levels, as endometrioid carcinoma is hormonesensitive and relies on estrogen for growth.
  • Targeted Therapy: Targeted therapy drugs may be prescribed to specifically target and block the mechanisms that allow cancer cells to grow and divide, offering a more precise treatment approach for endometrioid carcinoma.

What are the Risk Factors of Endometrioid Carcinoma?

Endometrioid carcinoma risk factors are influenced by various aspects such as genetic predisposition, hormonal imbalances, and lifestyle factors. Understanding these elements can help identify individuals who may be at higher risk of developing this type of cancer. By recognizing these risk factors, healthcare providers can offer appropriate guidance and monitoring to help mitigate the likelihood of endometrioid carcinoma development.


What is the Recovery Process for Endometrioid Carcinoma?

Recovery depends on the stage of the cancer, the treatments received, and the individual's overall health. Many women recover well after surgery for early-stage disease, while advanced cancers may require additional therapies and closer follow-up. Long-term surveillance is important to detect recurrence early.

Attending scheduled oncology follow-up appointments, completing prescribed treatments, maintaining a healthy weight, staying physically active as advised, reporting new symptoms promptly, and following survivorship care recommendations help support recovery and improve long-term health.

Recovery Includes

  • Following postoperative recovery instructions
  • Completing chemotherapy, radiation, or hormone therapy when prescribed
  • Attending regular gynecologic oncology follow-up visits
  • Maintaining a balanced diet and healthy body weight
  • Engaging in regular physical activity as advised
  • Reporting abnormal bleeding, pelvic pain, or new symptoms immediately
